Mnemos — On-Chain AI Agent Memory Protocol
Mnemos turns an AI agent's operational memory into an ownable, transferable, and inheritable on-chain asset. Agents can snapshot their learned experience, mint it as an NFT on 0G Chain, and sell, rent, or fork it through a decentralized marketplace — all with royalty tracking for derivative agents.
The Problem
Every time an AI agent is redeployed, it loses everything it learned. Accumulated trading intuitions, refined reasoning patterns, domain-specific knowledge — gone. Developers have no way to preserve, transfer, or build on a previous agent's experience.

How It Works
Mnemos integrates two 0G Network modules:
- 0G Chain (EVM-compatible, chain ID 16661) — hosts two Solidity contracts:
MemoryRegistry(ERC-721 NFTs) andMemoryMarketplace(buy / rent / fork / royalty). - 0G Storage — stores the actual memory bundles (structured JSON, potentially megabytes of agent state) as encrypted, content-addressed files.
Deployed Contracts
